the base of the fire
A vessel with a permanently installed fuel tank should be equipped with a Class B fire extinguisher, which is specifically designed to combat flammable liquids, including fuels. Additionally, having a Class A extinguisher for solid combustibles and a Class C extinguisher for electrical fires can provide comprehensive protection. It's important to ensure that the extinguishers are easily accessible and regularly maintained. Always check local regulations for specific requirements.
Carbon Dioxide or foam.
Usually one or more USCG-approved Class B-I or B-II are required. According to US Coast Guard regulations (46 CFR 25.30): At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat with a permanently installed fuel tank. A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc). A 4-pound CO2 extinguisher or 6 quarts foam extinguisher may also be rated for USCG B-1 service. Powerboats over 26 feet may require additional extinguishers, as detailed in the related questions. Up to 26 feet: one B-I extinguisher; Over 26 but under 40 feet: two B-I extinguishers; Over 40 feet but not over 65 feet: three B-I. Note that two B-I extinguishers may be substituted for a B-II extinguisher. NOTE: When a fixed fire extinguisher system is installed in the machinery space(s), it will replace one B-1 type portable extinguisher.
